Instead of a guestbook, have each guest highlight their favorite Bible verse and sign their name beside it. They will use this as their family Bible for years to come. LOVE this idea! - This is my favorite guestbook so far! (the guest book for me)
Update the wedding guest book with these unique ideas
Message in a bottle for anniversaries. Have wedding Guests write a note(s) and they can choose what year to personalize their note for. Then they stick it in the appropriate bottle! Married couple reads the notes on the matching anniversaries.
Assign each table a different anniversary year (i. table 1 would be anniversary year etc.) and let the guests at that table write notes to be opened on that particular anniversary year (a unique alternative to a wedding guest book).
